Finding the type of an object in C++?

13 Jan 2017 by Richard MacCutchan

C++ does not have any mechanism for detecting class types at runtime. You would need to add some extra properties to your classes. Alternatively there are some third-party libraries that may help; Google for "C++ reflection".Thanks to Carlo, I now know the correct answer.

Why is there no access to the port 0xCF8?

11 Nov 2015 by Frankie-C

To access ports from code you have to enable permissions for I/O access using ioperm() [^].Consider also that there are some issues with io.h and asm.h (see[^]). It is highly recommended to compile the code with optimization on when using I/O macros.

Why is there no access to the port 0xCF8?

11 Nov 2015 by Jochen Arndt

From the outl man page[^]:Quote:You use ioperm(2) or alternatively iopl(2) to tell the kernel to allow the user space application to access the I/O ports in question. Failure to do this will cause the application to receive a segmentation fault.
